I think it's a neat idea and device and I have been excited to get one as soon as it was mentioned, and you are right it is going to improve for sure. However the more I think about it this thing is going to have a very small use case, for a very small amount of specific people who want it.
It's not for me, I have way too many portables and also use a galaxy note 20 ultra with a razer kishi for portable emulation. I also have a gaming laptop for play around the house. I love taking my laptop anywhere and all games will look and play better on a 15inch screen.
My laptop was 550 bucks has a amd 560x graphics card which is to say it ain't cutting edge, I'd still never recommend a steam deck over it for gaming on account of all a laptop can do and it plays more steam games than a deck.
At this point the deck just seems like a jack of all trades master of none type deal that comes with moderate commitment for the user. And this device is more useful for a hardcore hardcore steam player, someone who already possesses a vast steam library.
